Step 4
Next, press the Create a New Layer icon on the bottom of the Layers palette. Choose the Brush tool and set the Foreground color to white. Set the brush size to 700 pixels, soft-edged.

Step 5
Click the brush once just along the side of the canvas.

Step 6
Click the Move tool and make sure Show Transform Controls is selected up on the Options palette. Click-and-drag the side of this layer to make it about this size and press Return (PC: Enter) to apply the changes.

Step 7
Next, click Cmd-J (PC: Cntrl-J) four times to duplicate this layer so we have five layers with the brush pixels we just created.

Step 8
With the top layer selected (Layer 1 copy 4), go to Filter>Distort>Twirl and set the twirl to -100 and click OK. With the Move tool, move this layer slightly to the right and we can see the effect.

Step 9Repeat step 8 but for the four other layers with the brush pixels on them: Layer 1 copy 3, Layer 1 copy 2, Layer 1 copy, and Layer 1. But instead of -100, set the Twirl to -50, 50, 100, and 150. Using the Move tool to move the layers around, we can see the various shapes.

Step 10
Next, rotate the various layers with the wavy shapes by hovering the mouse cursor near the corner of the transform controls and click-and-drag. Try various angles, my example looks like this.

Step 11
Click the Create a New Layer icon on the Layers palette, and click once with the Brush tool in various areas of the canvas with various colors. Change the Layer Blending Mode to Soft Light. Now we have a nice piece of art for a design.
